विकल्प

• Teraammoniumcobaltchloride

• Tetramninedichlorocobalt (III) chloride

• Tetraamninecobalt (II) chloride

• Dichlorotetraamminecobalt (III) chloride

Answer 1

Tetramninedichlorocobalt (III) chloride

Explanation:

Oxidation state of Co is given by - [Co(NH₃)₄Cl₂]⁺ Cl

∴ O. S. of Co = 1 − [(O. S. of 4 × NH₃) + (O. S. of 2 × Cl)]

= 1 − [0 − 2]

= 1 + 2

= +3

∴ Name is → Tetramninedichlorocobalt (III) chloride
